This project was an interdisciplinary, multi-institution collaboration centered on enhancing water resiliency in Texas by identifying Grand Challenges for understanding water resilience, comparing climate model projections at high spatial resolution to illuminate drought mechanisms, and developing scenarios for population growth, demographic change, and regional development in the 21 st century.

PUBLICATIONS PRODUCED AS A RESULT OF THIS RESEARCH The overarching goal of this research is to build knowledge regarding the factors that will impact future water resiliency in the rapidly changing human and natural systems of Texas, which will have applicability to other regions for which significant population growth and changing water availability are projected. New research activities will bring together researchers from complementary disciplines to initiate collaborations and synthesize research activities. The research comprises: 1) Identifying the Grand Challenges for understanding Texas water resiliency 2) comparison of 21st century climate model projections at high spatial resolution and improving our understanding of the mechanisms that drive drought in Texas 3) development of scenarios of demographic changes and regional development for the 21st century in Texas and 4) integration of the above into a regional evaluation of future water resiliency for the state. Thus, research will be conducted on climate, population, urbanization and water resources in this region, as it is a valuable proving ground for new techniques and strategies to address water scarcity.
100th meridian drivers#
It is because of these twin drivers of climate change and population/economic growth that the central Texas corridor can be viewed as a sentinel community that is, the changes that are currently underway in the region may predict trends for other parts of the U.S.
100th meridian driver#
Couple climate change with rapid population and economic growth, and man-made forces become an important driver of future water scarcity in times of drought. The central Texas corridor's position near the climatic boundary makes it particularly sensitive to changes in temperature and precipitation.
The state is projected to double in population by the year 2065. The major cities of San Antonio, Austin, Dallas, Fort Worth, and the Rio Grande Valley are located just east of the 100th Meridian, and rank among the fastest growing regions in the U.S. As such, the transitional boundary between the humid east and semiarid west is shifting eastward from the 100th Meridian. There is good agreement among climate models indicating a warmer and probable drier future for central Texas. Geological Survey director, popularized the 100th Meridian as the climatic boundary between the humid east and the semi-arid west - the geographic origin of the western United States.
